🤔 Как защитить Cookie от JavaScript?

Если cookie содержит чувствительную информацию (например, auth_token), важно защитить его от доступа через JavaScript. Иначе злоумышленник может украсть его через XSS-атаку (Cross-Site Scripting).

🟠Используем флаг `HttpOnly` (основная защита)
HttpOnly делает cookie недоступным для JavaScript (document.cookie). 

Set-Cookie: auth_token=abc123; HttpOnly; Secure; SameSite=Strict


🟠Используем `Secure`, чтобы cookie передавались только по HTTPS
Флаг Secure запрещает передачу cookie через HTTP, только HTTPS. 
Set-Cookie: auth_token=abc123; Secure


🟠Используем `SameSite`, чтобы защититься от CSRF-атак
SameSite=Strict или SameSite=Lax защищает от подделки запросов (CSRF). 
Set-Cookie: auth_token=abc123; SameSite=Strict


🟠Не храним токены в cookie (если можно)
Если возможно, используйте Authorization: Bearer заголовки вместо cookie. 
Authorization: Bearer abc123

Spiking bond yields driving sharp losses in tech stocks

A spike in interest rates since the start of the year has accelerated a rotation out of high-growth technology stocks and into value stocks poised to benefit from a reopening of the economy. The Nasdaq has fallen more than 10% over the past month as the Dow has soared to record highs, with a spike in the 10-year US Treasury yield acting as the main catalyst. It recently surged to a cycle high of more than 1.60% after starting the year below 1%. But according to Jim Paulsen, the Leuthold Group's chief investment strategist, rising interest rates do not represent a long-term threat to the stock market. Paulsen expects the 10-year yield to cross 2% by the end of the year. A spike in interest rates and its impact on the stock market depends on the economic backdrop, according to Paulsen. Rising interest rates amid a strengthening economy "may prove no challenge at all for stocks," Paulsen said.
